TRUSTECH 5A Overcurrent Protection Sensor Module AC current detection sensor 12V relay Switch Electronic Components Electronic Hobby Kit

Using Instructions: By setting the potentiometer to set the overcurrent protection point, the clockwise adjustment reduces the detection current. As bellows: 1. Measured the wire through the current transformer , connect VCC and GND to DC12V power supply; 2. Adjust the potentiometer, when you hear the sound of the relay pull (can be measured with a multimeter COM and NO whether was turned on, if connected to the relay means activated)||Functions: -Current detection resolution can change the parameter of resistance parameters; -Output over-current switching signal output; -Over-current signal setting critical point adjustable.;Specifications: Operating voltage: DC12V Operating current: <20MA Operating frequency range: 20Hz ~ 400Hz Output mode: switch signal output Maximum detection wire diameter: 5.2mm Mounting hole: hole diameter is 3mm, hole distance is 52.5mm Operating environment: -40 ℃ ~ +85 ℃ The current detection range :AC0.3A-5A Board size: 38 * 44mm;then reduce or cut off the current flowing that through the tested wire , if the relay release at this time that over-current protection point has been identified (available to multimeter COM and NC measurement whether is connected, if connected to the relay means been released); 3. When reduce or cut off the current flowing through the wire , the relay is not released, will still need to continue to adjust the potentiometer to find the over-current protection point
